<strong>SWL</strong> SERIES - <strong>SWL</strong><strong>750</strong><br />
<strong>SWL</strong> Valve Regulated<br />
Lead-Acid Batteries (VRLA)<br />
The <strong>SWL</strong> range is an enhanced NPL design resulting<br />
in an improved energy to density ratio, giving up to<br />
40% extra discharge capacity. All other attributes and<br />
operational characteristics are the same, thereby<br />
maintaining the benefit of a common mechanical and<br />
electrical design for users of both products.<br />
FEATURES<br />
• Yuasa VRLA batteries can be used in any orientation<br />
excluding continuous use inverted.<br />
• Standard case material is flame retardant to (UL94) HBØ.<br />
• FR option case material is flame retardant to UL94:VØ<br />
(oxygen index 30).<br />
• <strong>SWL</strong> batteries are manufactured in factories that comply<br />
with ISO9001:2000.<br />
• FR option <strong>SWL</strong>’s comply with BS6290 Part 4 (1997).<br />
• <strong>SWL</strong> batteries comply with IEC 60896-21+22.<br />

- Service life and operational characteristics will be<br />
affected by temperature.<br />
- AC Ripple reduces service life.<br />
WARNING!<br />
<strong>SWL</strong> (Standard) and (FR) battery types <strong>SWL</strong>1850;<br />
<strong>SWL</strong>1850-6; <strong>SWL</strong>2500, must never be installed permanently<br />
suspended by their handles; they are not<br />
designed for this purpose.
